' 11 claims. `(o1. 12s-9s) 'Ihese objects I have achieved successfullyin actual practice, and by the means fwhich are 15 hereinafter describedand claimed, and which are illustrated one exemplication in theaccompanying drawing, which is a side elevation, in

perspective and with parts broken away, of' a lhover for chickensincluding in the heating means 20 my improved superheater coil.

It is to be understood that minor modifications `of this invention arewithin the scope of the .appended claims, and/that the return coil ofthe device exemplified may beincorporated in any 25 species'cf `heatingapparatus to which it will be applied where Afuel is burnedv and thepartially icoinbined gases o f combustion passed through the coil. f Y

VIn the'drawinvg, the-nLuneral 1 denotes a pair 30 of angular legsadaptent@ be mounted fixedly` uponany suitable supporting base, andhaving top rings 2 encircling andsecured to the pair ofvertically YerectreceiViIlg and delivery end members and 6 respectively 0f horizontallydisposed 35 parts of a convoluted intermediate tube or pipe 3. A hovercover 4 is shown mounted also on said legs above the convoluted pipepart 3 and traversed by said members thereof 5 -and l6.

The numeral 8 denotes an elongated rectangu- 40 lar or oblong housingcontaining a similarly shaped reservoir 19 for liquid fuel. At the rearthe top and bottom of said housing has vertically alined apertures at 10and 9, the aperture 10 also the aperture 9 being traversed by the longerg .1.45 member 6 of said f pipe, the member fitting the upper aperturel0 but being of less diameter than the lower aperture 9. At the frontpartA of the bottom ofthe housing is provided a fitting aperture for theupper termination of the erectfor- 50 ward pipe member ,5, `whereby the,open top of the inlet pipe 5 communicates with the front inside of thehousingA 8.

The forward part of said housing has a low transverse front wall 11.vAbar 16, hooked at '55 the top is suspended removably inthe open toptube 5 and carries atfits lower end an 4open cup 14 having a centraldepending leg 15 to support it in .spaced relation on the bottom coilend. An apertured dropper concaved plate 23 '60 secured adjustably by ascrew 24 on the bar 16 receives liquid fuel from a spigot of a tank':

19, to deliver it in fine drops into the lower cup 14. Y

The open front of the housing has its sides 12 'sloped downwardly andhas a hinged cover 13 The tank 19 has the spigot 20 governed by a withhasp to engage a pinV 18 onthe wallfll.

valve 2l, with nozzle 22 to'deliver fuel upon the Vplate 23.

The structures thus described are substantially those shown in mypending application for Pat'f ent Serial No. 357,133, filed April 22,1929.

My principal improvement over said application consists in supplying aninclined cross tube 7 from the reartube or riser 6 immediately below thehousing 8 and to the forward riser tube 5 a"-" little above itsconnection with the coil and also above the fuel cup 14. The tube 7 isshown of less diameter than the'risers but may be of the same diameter.

The operation of the device is as follows: Open the valve of the spigot20 to permit liquid fuel from the supply tank 19 to fall downwardly inthe vertical inlet pipe 5.? This liquid will strike the member 23 and bedelivered in fine drops to the cup 14. After igniting the fuel, the lid13 should be closed. With the apparatus in operation fresh air willenter the housing 8 between the outline of the aperture `9 .and the`outlet pipe 6.' This air by coming in contact with the outside of theoutlet pipe 6, which extends through the housing 8, will become heatedand as it passes rearwardly in the housing 8 to enter the inlet pipe 5,it will notonly furnish warm air for the proper burning of the fuel oil,but will warm the fuel oil in the supply tank 19. 3 of the device shouldbe of suicient length to provide efficient combustion of the fuel oilbefore the gases from the same pass into the outlet pipe orv flue 6.However, as is well known, many valuable heat units in the form of fueldo escape from the outlet pipe of an oil burner and to care for theseotherwise lost products of combustion, I have provided the cross pipe'7. This pipe draws off the escaping products of combustion, hot air andgases from the pipe 6 and returns the same to the inlet pipe 5 at apoint above the combustion point of the apparatus. This flow of valuableelements through the pipe '7 is caused bythe suction in the pipe 5 asdistinguished from the lack of suction in the pipe V6. This suction inthe pipe 5 is caused by the down- .ward flow of the fuel oil and air inthe pipe 5.

The convoluted part it for eicient results. The cup 14 and member 23maybe easily removed from Vthe pipe 5 and replaced as easily.

Having described my invention, what .I claim as new, and desire tosecure by Letters Patent, is:
